Hm... actually I've been using cmake already... Anyway, I tried to run
cmake only for the volk component manually:
address@hidden gnuradio]$ cd volk/
address@hidden volk]$ mkdir build
address@hidden volk]$ cd build/
address@hidden build]$ cmake -D GR_RUNTIME_DIR=bin ..
/.../
address@hidden build]$ make
/.../
address@hidden build]$ apps/volk_profile
Using Volk machine: avx_64
RUN_VOLK_TESTS: volk_16ic_s32f_deinterleave_real_32f_a
Illegal instruction
Perhaps you meant to not use cmake? Can you provide the specific build
instructions I should try?
Thanks,
joanna.
